A MYSTERIOUS LETTER IGNITES AN EXPLOSIVE CHAIN OF EVENTS FROM THE SOUTH CAROLINA LOWCOUNTRY TO THE OUTER BANKS. An execution-style murder next to the Port of Charleston triggers an intensive police investigation to find a killer. In an apparently unrelated incident a year later, three complete strangers each receive an anonymous letter offering a financial windfall with a detailed set of instructions...and an ominous threat for failing to comply. The strangers must travel alone from Charleston to Daufuskie Island off the coast of Hilton Head, South Carolina. Hoping to find answers, they instead become pawns in a clever and elaborate scheme planned by the ruthless boss of a Miami drug cartel. When Detective Steve Harris finally discovers the crucial link between the murder and the missing strangers, he launches a frantic race against time, the cartel, and a deadly hurricane, to find them before they disappear for good.
